Why do AC capacitors fail?
Any time the power surges, the increased voltage will negatively effect the components in your air conditioner and can damage them to the point that they can no longer function properly. AC capacitors aren’t designed to handle the heat and surge from these situations and can inevitably fail.
Can a power surge cause a capacitor to fail?
Power surges can cause a capacitor to fail, too. Obviously a lightning strike from a summer thunderstorm can overload and burn out your HVAC’s electrical system., Also weaker power surges can cause damage to capacitors over time. Those weaker surges can be caused by fluctuations in the electrical grid.
What causes a faulty capacitor to stop working?
This delay is often caused by the capacitor’s inability to deliver the necessary power quickly. Additionally, if you notice a decrease in the overall performance of your electronic devices, such as slower processing speeds or decreased functionality, a faulty capacitor may be to blame.
Is my AC capacitor going bad?
In general, if your air conditioner isn’t running quite right, that’s a sign that your capacitors may be going bad. It may be tempting to put off calling for service if the AC still seems to be working at least some of the time. Here’s why that’s a really bad idea. When a capacitor begins to fail, the repair is relatively inexpensive.
